A. protect the wire from the sun
B. prevent electrocution
C. provide flexibility
D. provide strength
2. welding electrodes used for SMAW process except:
A. E6010
B. E6011
C. E7018-B2L
D. E71T-1
The reason for insulation on the welding lead is to insulate the conducting wires of the cable so that it may not be dead shorted to ground before the electricity can be tapped at the jaws of the electrode holder and complete the welding circuit thru the electrode to the work piece and then to the ground. "D" is your second answer, Best that you should reread your homework assignment because you do not have a very good comprehension of your reading assignment.First 3 selections are welding electrodes for the SMAW Process. I would recommend that you think about another trade other than welder or metal fabricator.
